Hi @jfboeve

Usually we used to follow the below format whenever we create a release

Changes

Merged : This section tells about the merged in changes

Todo - This is the checklist

• Update CHANGELOG.md
• Update docs/changelog.md
• Update package.json and package-lock.json
• Update docs/package.json

I think the package json inside the docs folder is not updated to the latest version :-)
